Coal is a fossil fuel that has been used for centuries to generate heat and electricity. Its abundance, low cost, and high energy content make it an attractive fuel source for thermal power plants. In a coalfired power plant, coal is pulverized to a fine powder and then burned in a boiler to produce steam.
